Synthesis and Properties of Hg Diyne/Poly-yne and Au Diyne Complexes Containing 9-Butylcarbazole Unit

Three new d~(10) Hg and Au poly-yne and its diyne containing 9-butylcarbazole unit were synthesized by dehydrohalogenation reactions and characterized by()~1H NMR,()~(13)C NMR,()~(31)P NMR,FTIR,FAB-MS,UV-Vis,fluorescence and phosphorescence spectroscopies.All the compounds were analytically and spectroscopically characterized to possess a well-defined size and structure.The materials are organic-soluble and solution-processable.The results show that the organic triplet emission can be harvested by the heavy-atom effect induced by Au and Hg which can efficiently promote the intersystem transition from the S_(1)singlet excited state to the T_1 triplet excited state.The relationship between the T_1 energy state and the intersystem transition for the system was discussed.It is envisioned that a structure-property-function relationship can be established and valuable insight into the photophysical nature of conjugated materials can be subsequently derived.
